> According to the Python documentation (
> http://docs.python.org/c-api/intro.html#includes), the include directive
> for “Python.h” should appear first in the C/C++ file.
> It doesn’t sound like a good idea to require this, but if you don’t put
> “Python.h” first, you might get compiler warnings like I mentioned above.

> I've made a diff (against kamailio-3.3.2) for fixing that.
